Release 0.8.8 is a minor release and contains a bugfix for HSM, a feature for `GraphSupport` and changes internal cache handling:
- Bugfix #544: `NestedEvent` now wraps the machine's scope into partials passed to `HierarchicalMachine._process`. This prevents queued transitions from losing their scope.
- Feature #533: `(A)Graph.draw` function (object returned by `GraphMachine.get_graph()`) can be passed a file/stream object as first parameter or `None`. The later will result in `draw` returning a binary string. (thanks @Blindfreddy).
- Feature #532: Use id(model) instead of model for machine-bound caches in `LockedMachine`, `AsyncMachine` and `GraphMachine`. This might influence pickling (thanks @thedrow).
